Infineon Technologies CY7C1413KV18-300BZXC

Overview

CY7C1413KV18-300BZXC from Cypress Semiconductor is a 2 M × 18, 36-Mbit QDR® II SRAM with four-word burst architecture, 300 MHz clock operation (600 MHz DDR data rate), 1.8 V core supply, and 1.4–1.8 V I/O supply. It features separate read/write ports, echo clocks (CQ/CQ), and programmable DOFF for 1-cycle or 1.5-cycle read latency-used in high-bandwidth packet buffering for network switches and routers.

For engineers reviewing the CY7C1413KV18-300BZXC datasheet, CY7C1413KV18-300BZXC pinout, CY7C1413KV18-300BZXC application, or CY7C1413KV18-300BZXC equivalent, key selection criteria include QDR II burst timing compliance, FBGA-165 package compatibility, dual-clock domain synchronization (K/K and C/C), and 18-bit wide synchronous interface support for telecom line card memory subsystems.

Technical Context

This SRAM implements true QDR II architecture with physically independent read and write data paths, eliminating bus turnaround overhead. It uses two rising-edge-triggered input clocks (K and K) for address/data latching and two output clocks (C and C) for synchronized data capture-enabling concurrent read/write operations at full bandwidth.

The device integrates an on-chip PLL for precise data-eye placement and supports both single-clock mode (K = C) and dual-clock mode. Its 19-bit address bus accesses a 2 M × 18 memory array organized as four 512 K × 18 banks, with BWS[1:0] enabling byte-selective writes to D[17:0].

FAQ

What is the function of the DOFF pin on CY7C1413KV18-300BZXC?

The DOFF (Data Output OFFset) pin selects read latency mode: when asserted HIGH, it configures 1.5-cycle latency for relaxed timing margins; when LOW, it enables 1-cycle latency for maximum throughput. This setting directly affects the number of clock cycles between address assertion and valid Q[17:0] output, and must be held stable during operation - it is not dynamically switchable mid-burst.

Can CY7C1413KV18-300BZXC operate in single-clock mode?

Yes - by tying K = C and K = C, the device operates in single-clock mode where one clock drives both address/data capture and output timing. In this configuration, echo clocks CQ/CQ remain functional but track the single clock, simplifying system clock tree design at the cost of reduced flexibility in read/write timing skew management.

What is the purpose of BWS[1:0] pins?

BWS[1:0] are active-low byte write select inputs that enable partial-word writes: BWS0 controls D[8:0], BWS1 controls D[17:9]. When either is deasserted, the corresponding 9-bit byte is ignored during write cycles - preserving existing data without requiring a read-modify-write sequence. This is essential for efficient header/metadata updates in packet processing.

Is JTAG boundary scan supported on CY7C1413KV18-300BZXC?

Yes - the device implements IEEE 1149.1 JTAG TAP controller with TDI, TDO, TCK, and TMS pins. It supports instruction register loading, boundary scan register access, and IDCODE readout. JTAG functionality is enabled by default at power-up and can be disabled via the TAP instruction register if unused - no external hardware modification is required.
